Abstract

S/MIME (Secure/Multipurpose Internet Mail Extensions) provides a consistent way to send and receive secure MIME data. Based on the popular Internet MIME standard, S/MIME provides the following cryptographic security services for electronic messaging applications: authentication, message integrity and non-repudiation of origin (using digital signatures) and privacy and data security (using encryption).

1. Introduction

S/MIME (Secure/Multipurpose Internet Mail Extensions) provides a

consistent way to send and receive secure MIME data. Based on the

popular Internet MIME standard, S/MIME provides the following

cryptographic security services for electronic messaging

applications: authentication, message integrity and non-repudiation

of origin (using digital signatures) and privacy and data security

(using encryption).

S/MIME can be used by traditional mail user agents (MUAs) to add

cryptographic security services to mail that is sent, and to

interpret cryptographic security services in mail that is received.

However, S/MIME is not restricted to mail; it can be used with any

transport mechanism that transports MIME data, such as HTTP. As such,

S/MIME takes advantage of the object-based features of MIME and

allows secure messages to be exchanged in mixed-transport systems.

Further, S/MIME can be used in automated message transfer agents that

use cryptographic security services that do not require any human

intervention, such as the signing of software-generated documents and

the encryption of FAX messages sent over the Internet.
